SPECIFICATION forming part of Letters Patent No. 787,838, a ed April 18,1905.

Be it known that I, TALBOT (J. Dux'rnn, a citizen of the United States,residing at Pearl River, in the county of Rockland and State of NewYork, have invented certain new and useful Improvements in PaperAssembling, Stitching, and Folding llachines, of which the following isa specification.

This invention relates to improvements in the class of machines designedto assemble, secure together, and fold a plurality of sheetsconstituting a periodical or pamphlet, and particularly to the style ofmachine covered by my previous patents, Nos. 588,635, 595,941,599,53l1l, ($02,816, 618,64e8, 632,4H8, 653,196, and lEt'rOJQ C. In thistype of machine as hereto fore constructed and as disclosed in thepatents mentioned the sheets or signatures and cover which are to beassembled, bound, and folded into a pamphlet are fed into the ma chineat a plurality of points and gathered or assembled at a single point ofassemblage, and the sheet-actuated controlling devices are arranged inthe paths of the individual sheets or signatures and cover to controlthe disposition of the assembled sheets or signatures and cover at thepoint of assemblage, the absence of any one of the parts of the pamphletpermitting the operation of the controlling de vices for throwing out ofthe machine the remaining parts of the pamphlet which have been fed intoposition, so as to thereby avoid the binding, folding, and delivering ofan incomplete book. \Yith this type of machine as heretofore constructedthree signatures or parts is about the largest number that can behandled practically because of the necessity of feeding each sheet orsignature inde'pendently to the point of assemblage. The capacity ofthis old type of machine is therefore limited.

The main feature of novelty in my present invention consists inproviding a plurality of sheet or signature assembling mechanisms whichare so constructed and arranged that they will assemble sheets orsignatures at a plurality of points, one of the points being the commonpoint of assemblage at which all g to the stitching mechanism.

of the sheets or signatures of a book or pamphletare collectedpreparatory to being passed 5 Suitable controlling devices are providedwhereby the sheets or signatures assembled at one point will control thedisposition of the sheets or signatures assembled at another point, andpreferably the sheets or signatures which are lirst assembled willcontrol the disposition of the sheets or signatures which aresubsequently assembled.

In a machine crmstructed in accordance with my present invention thesheets or signatures and cover which are to constitute the book orpamphlet to be produced are fed in at a number of convenient points andare conveyed by subauxiliary conveyors to auxiliary conveyers on whichthey are assembled in twos or threes and the assembled parts thenconveyed by the auxiliary conveyers to a main conveyor, upon which theseveral sheets or signatures and collections of previously-as- 7osembled sheets orsignatures are assembled as a whole and transferred tothe stapling or stitching machine and the final-folding and deliveringmechanisms. This novel form of machine also includes automatic sheet orsignature controlling devices for the auxiliary conveyors actuated bythe imlividual sheets or signatures carried by the subauxiliaryconveyors, so that the absence of any individual sheet or signature atthe point of lirst assem- 0 blage on an auxiliary conveyer will permit adevice to be operated to throw out of the machine the remaining sheetsorsignatures which have reached the auxiliary conveyor. in addition tothe auxiliary controlling devices 1 provide the main automaticcontrolling devices which are actuated by the sheets or signatures orcollections of sheets or signatures carried forward on the auxiliaryconveyers and control the main-shectaletlecting switch andstitchingmachines, so that the absence of any sheet or signature or anycollection of sheets or signatures which should have been carriedforward by the auxiliary conveyors will permit themain-sheet-detlectingswitch to throw out of the machine the sheets orcol-
